Review on LimoStudio 2-Pack of 105-Watt Photography Fluorescent Bulbs for Daylight-Neutral Tone, Full Spectrum Lighting Efficiency in Photo/Video Studio - LMS121 by Chris Doe

I bought these for my LimoStudio Octagon flashlight. He uses this model where the bulb is much larger than average. The luminous flux becomes bright very quickly. It heats up, but does not emit heat. With it I have a great light even in pitch black darkness and when using the flash of my camera. My only issue was that one lightbulb didn't work right out of the box. So check both ads when you get them. The seller responded quickly and sent me a replacement. I will give this 5 stars when I have a replacement and see if they last long enough to be worth the money.
